so have anyone can prove how many days you stay in Thailand? There is no information exchange inside Thai offices. Anybody who thinks taxes are a problem for retired people or long term tourists are a problem don't know anything about Thailand or taxes. Even in Europe there is no chance of tracking anyone if not employed or registered in a company. Discussions about nothing!
sorry but I just found out that the Konsul in Chiang Mai overcharged me for my new passport as I am outside Germany for 33 years and he showed me only 1 price line when I been there.
